Summary: Petition for Approval of the Power Cost Adjustment (PCA) Mechanism Annual Report for calendar year 2016. Actual power costs were higher than baseline average power cost rates in effect during 2016 creating an under-recovery of $2,058,382. Due to the operation of the PCA’s sharing mechanism, PSE absorbed the entire overage. The cumulative deferral balance for the PCA is $4,324,648 in the surcharge direction. No refunds or surcharges are instituted until the deferral balance reaches a threshold of $30 million in either direction.
